How to set default visible columns in posts list, for all users

Question

Is there a way to set default visible columns in posts list, for all users?

Answer 1

Since the question was about columns and not meta boxes and I needed this solution, Ioannis’ reply got me on the right track.

The filter hook in question is default_hidden_columns.

This is the solution I ended up with to set my ad_shortcode column to be hidden by default. You should know that this is just the default. As soon as the page was visited, the default is no longer be used. Look for a meta key that includes columnshidden in wp_usermeta and remove it when testing.

add_filter( 'default_hidden_columns', 'hide_ad_list_columns', 10, 2 );
function hide_ad_list_columns( $hidden, $screen ) {
    // "edit-advanced_ads" needs to be adjusted to your own screen ID, this one is for my "advanced_ads" post type
    if( isset( $screen->id ) && 'edit-advanced_ads' === $screen->id ){      
        $hidden[] = 'ad_shortcode';     
    }   
    return $hidden;
}

To change the defaults, you simply need to hook into the default_hidden_meta_boxes filter and supply your own PHP array listing the meta boxes you’d like hidden by default. In the example below, I hide the author meta box and the revisions meta box. This way, they’re hidden for users unless they’ve decided to enable them in Screen Options.

  <?php
/**
 * vpm_default_hidden_meta_boxes
 */
function vpm_default_hidden_meta_boxes( $hidden, $screen ) {
    // Grab the current post type
    $post_type = $screen->post_type;
    // If we're on a 'post'...
    if ( $post_type == 'post' ) {
        // Define which meta boxes we wish to hide
        $hidden = array(
            'authordiv',
            'revisionsdiv',
        );
        // Pass our new defaults onto WordPress
        return $hidden;
    }
    // If we are not on a 'post', pass the
    // original defaults, as defined by WordPress
    return $hidden;
}
add_action( 'default_hidden_meta_boxes', 'vpm_default_hidden_meta_boxes', 10, 2 );
